Matek G474-HELI RC Heli Flybarless Flight Controller

Unveil the skies with the Matek G474-HELI, a trailblazing flight controller designed specifically for Flybarless model helicopters. This unit marks Matek's first foray into the realm of rotor-powered flight, bringing precision and control to your aerial endeavors.

Key Features:

• Advanced Processing Power: Equipped with the STM32G474CE MCU, this flight controller operates at a swift 170MHz. Its Cortex-M4 core and 512KB Flash memory ensure robust performance and smooth, responsive flight controls.
• High-Resolution IMU: With the ICM42688-P IMU, pilots enjoy accurate flight data, essential for maintaining stability and maneuverability in diverse flying conditions.
• Atmospheric Monitoring: The onboard SPL06 barometer provides real-time atmospheric data, crucial for altitude control and weather assessment.
• Enhanced Connectivity: Features include three UARTs ports, a single I2C interface, and eight PWM outputs (including four for servos and two for motors), allowing extensive peripheral and sensor integration.
• Reliable Power Management: Power input ranges from 5.4V to 30V, compatible with 2-6S LiPo batteries. It includes dual BEC outputs—one 5V 2A for flight controller and peripherals, and another adjustable Vx 5A (continuous) / 8A (peak) for servos.
• Comprehensive Firmware and Storage: Runs on the efficient RotorFlight firmware and includes a 128MB BlackBox for thorough flight data logging.
